Mechanism of efficiency of DMDC DMDC can permeate through the cell membrane, and block the metabolism through reacting with the enzymes of microorganism, then achieve the purpose of sterilization. Even in very low additive amount, DMDC can effectively kill typical spoilage bacteria in beverage, and not affect the taste, flavor and color of the beverage. Furthermore, it could be rapidly and completely hydrolyzed to carbon dioxide and methanol, which are the natural ingredients of juice.

Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.

Lump sulfur, also known as granular or rock sulfur, is typically characterized by a purity of 99.80% or higher, with a maximum ash content of 0.05%.
It should also have a limited acidity (H2SO4) of 0.02% or 0.03% and minimal moisture content (0.5% or 0.2%).
More detailed breakdown of lump sulfur specifications:
Purity:
Dry Basis: 99.80% minimum purity is a common specification.
Other Standards: Some standards like Refinery Specifications, may specify a purity of 99.98%.
Impurities:
Ash Content: A maximum ash content of 0.05% is a typical requirement.
Acidity: A maximum acidity (H2SO4) of 0.02% or 0.03% is common.
Organic Substances: Some specifications limit organic substances to 0.01% or 0.03% maximum.
Moisture: A maximum moisture content of 0.5% or 0.2% is generally specified.
Mechanical Impurities: Some specifications require the absence of mechanical impurities like paper, wood, or sand.
Other Impurities: Some standards specify limits for arsenic, selenium, tellurium, and lead impurities.
Color and Appearance:
Color: Bright yellow is the typical color specification.
Other Considerations:
Test Methods:
Specifications often include test methods, such as ASTM D-4239, ASTM D-1509, ASTM D-1613, and ASTM D-2790, for determining the various parameters.
Bulk Density:
Granular sulfur has a bulk density of around 70 lb/cu ft (1121.29 kg/cu m).
Solubility:
Sulfur is insoluble in water, partially soluble in acetone, and slightly soluble in diethyl ether and alcohol.
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3 )2SO.
It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point.
